Theory & Troubleshooting
Unlike many trades, refrigeration is uniquely challenging and interesting. The thing that makes this such a challenge is the fact that the process takes place out of sight. Solving refrigeration problems takes on a kind of nerdy "who-done-it" process. You can't see with your eyes what is going on, so you have to rely on test instruments, reference data, symptoms, and a "solid base" understanding of refrigeration theory to be able to troubleshoot problems.
I've seen valuable refrigeration equipment destroyed because so-called "technicians" didn't know what they were doing. I've also seen HVAC technicians condemn perfectly good equipment because they didn't have that "solid base" understanding of refrigeration.
Many successful refrigeration technicians mentally put themselves into the process. They start to think like a molecule of refrigerant. They visualize themselves racing through the various circuits of a refrigeration system, picking up heat here, giving off heat there, changing from a liquid to a gas, and visa-versa. They compare what is happening with what should be happening. It's this "think like a molecule of refrigerant" that allows them to solve the problems that others can't.
We teach a course called "Refrigeration Theory & Troubleshooting ~ "Solid Base" Fundamentals". For the duration of the class, we hammer home the basic refrigeration cycle until every person starts thinking like that molecule of refrigerant. We cover every nook and cranny of the basic refrigeration cycle until we know the system inside and out. The meaning of terms like saturation, super heat, sub cooling, compression ratios, slide, dew point, bubble poing, and flash will become crystal clear.
This is not an easy course, and it requires a lot to pass the final exam. For those who think they can absorb this technology.... welcome, we look forward to having another high quality technician in the field.
The "Refrigeration Theory & Troubleshooting" course runs for a minimum of 12 hours, and can be scheduled evenings, or days. Class size ranges from 10 to 16 students.
